How to choose medical high-efficiency filters

How to choose a medical high-efficiency filter? Believe thisis ManyUse an air filterManufacturer都willproblems faced, The author combines many years of experience todayHere with everyoneShare it.

Hospital air filter application areas mainly include: hospital transplant warehouse, hospital central supply room, hospital laminar flow room, hospital computer room, hospitalPICU/NICU, hospital cord blood bank, hospital surgery room, hospital intensive care unit, fluid distribution room, hospital corridor, hospital fan outlet, etc.

It can be seen from these places that hospitals can be roughly divided into ordinary environments, medium environments, and high-demand environments.

Ordinary environments, such as corridors, computer rooms, and fan outlets, are generally equipped with primary filters（For example, primary effect plate filter, primary filter Effective metal mesh filter, primary effect pleated filter).

In the central supply room and liquid distribution room, you can choose medium-efficiency filters（For example, medium-efficiency bag filter, medium-efficiency box filter Device).

Intensive care units, operating rooms, and cord blood banks must be equipped with high-efficiency filters(For example, high-efficiency non-partition filter, high-efficiency aluminum partition Filter).

1. How to choose a high-efficiency filter

1. High-efficiency filters are mainly used to capture dust particles below 0.3um and various suspended particles. things. Ultra-fine glass fiber paper is used as the filter material. Each unit has been tested by the flame method. It has the characteristics of high filtration efficiency, low resistance, and large dust holding capacity. High-efficiency filters include high-efficiency filters with partitions and high-efficiency filters without partitions. High-efficiency filters with partitions include: high-efficiency filters with partitionsAirFilters, high-efficiency filters with high temperature resistance, high-efficiency filters with high humidity resistance, high-efficiency filters without partitions include：Combined high-efficiency filter , no partitions and high efficiencyairfilter, liquid tank high-efficiency filter without partitions, ultra-low resistance high-efficiency filter without partitions, knife holder High-efficiency filter without partitions, ultra-high-efficiency filteretc..

2. The high-efficiency filter is at the end At the air supply area, when designing and selecting high-efficiency filters, they should be selected from low to high to protect the service life of filters at all levels. For example: G-level filtration → F-level filtration → H-level filtration → U-level filtration.

3. Commonly used frames for high-efficiency filters are ：Plasticframe, catalpa-plated frame, aluminum frame, stainless steel frame. The selection of the outer frame of the high-efficiency filter directly affects the price of the high-efficiency filter. Under different conditions, the quotations of high-efficiency filters with different outer frames are different.

4. For example, in high-temperature sterilization production clean equipment or ovens, it is necessary to use high-efficiency high-temperature filters. Glass fiber filter materials and high-temperature-resistant special rubber seals can withstand high temperatures, and the instantaneous high temperature can reach Above 300 degrees. Of course, the price and cost of high-temperature resistant high-efficiency filters are different from those of ordinary high-efficiency filters, because they depend on different glues.

5. For high-efficiency filters that need to be used in high-humidity and high-temperature environments, high-temperature and high-humidity-resistant filter paper and filter paper must be selected. Partition boards and frame materials must be used to meet production requirements. Biological clean rooms and medical clean rooms must use filters with metal frames, and their surfaces must be difficult to rust. Filters with wooden frames are not allowed to be used. Prevent the generation of bacteria and affect the qualification rate of products.

2. Installation of high-efficiency filter

1. Before installing the high-efficiency filter in a pharmaceutical factory, the clean room must be thoroughly cleaned and wiped. If there is dust inside the purification air-conditioning system, it should be cleaned and wiped again. Clean and meet the cleaning requirements.

2. Direction of high-efficiency filters in pharmaceutical factories It must be installed correctly according to the inlet and outlet directions of the high-efficiency filter, and cannot be reversed.

3. High-efficiency filters in pharmaceutical factories During transportation, handle with care and avoid severe vibration and collision. Do not force loading and unloading.

4. Pharmaceutical factory high-efficiency filter framework It should be flat.

5. High-efficiency filters must be used in pharmaceutical factories Replacement can only be done after stopping the air supply from the air conditioning system;The sealing gasket between the filter and the connection frame must be tight and leak-free to ensure Guaranteed filtering effect.
